Please forgive me for not having before shots for this project but picture a very cheap, thin white shade. I disliked it every time I walked by and knew I could do better. So up to the craft room I went.
In my stash I found some muslin. I pictured a burlap-like wrapped shade. But there was only enough muslin to wrap half the shade. To cover up the other half, I began cutting strips and gluing them on. Then I loosely knotted one of the strips. It looked pretty good. I added a few more knotted strips (5 in all) and viola!
I love the texture of the fraying muslin and the knots.
